If you're looking for another bike "just because" then I'd take a look at a Cannondale EVO. I have the slightly older Cannondale HiMod and it's an awesome bike. Confidence inspiring beyond belief and despite having tree trunk sized tubes that seemingly transmit every ounce of power you put into the bike, it rides very smoothly indeed. The EVO is said to be even better... I have never ridden a Boardman bike - I have ridden a road version of the Lotus Bike though similar to the one that Boardman smashed everyone enroute to the fastest Tour prologue in history... 
That said, you already have a really nice road bike that's more than capable of doing Lands end to John o Groats.
Especially with you having to live with colitis, I'd look at ways to make your cycling more productive and possibly less stressful. It's bad enough without wonky guts to go too hard and end up smashed out your brains after a hard day - and apart from the odd race many years ago where I hard to race with dodgy guts, I can't imagine doing that all the time. Just for that reason alone I'd opt for the powermeter - it allows you to be frugal yet effective with your efforts when riding. But I guess I've said that already...
Too true!

HMMMmmm ...
YOU could be right that my concerns about
tactile feedback which the Di2 shifters have-or-don't-have are unwarranted ...
Actually, you ARE right!
Unfortunately, my inclusion of
second hand information IS indeed fretting over something which 'I' cannot directly testify to ...
So, whether or not some of us may be manually clumsier than others when fatigued is possibly only a concern for the few of us rather than a concern for the many ...
It's the "
Once bitten, twice shy" problem that 'I' have with Shimano's mechanical shifters which makes
me wary of their engineer's sense of what is-and-isn't good ergonomicst, so my
spidey senses where apparently overly active ...
Remember, 'I' am the
princess-and-the-pea who was occasionally confounded by what 'I' feel is the (
unnecessary) "dwell" designed into Shimano's shifters ...
I just have to believe that there have-been-and-are
never-to-be-seen-by-the-public prototype versions of their STI Road shifters which have
concentric take-up spools!
So, chalk it up to my (
possibly?) amplifying the minute ...
And so, whether or not there is a lack of "feel" OR other possible concerns cited
by others who initially reviewed the shifters could-and-should indeed be described as "prattling."
And so, my apologies for the "prattling on."
Nonetheless (
because I apparently keep my components forever -- heck, I am still working on indexing a Nuovo Record rear derailleur to some Ergo shifters ... one tentative ""combination" seems to work, but ...), if you will allow me, I guess THAT raises the question as to how many times the buttons/("
switches") can be.activated before they fail?
2mm (?) of movement for the buttons does seem like a lot, but then again, not really that much ...
Keyboard switches fail.
Even touch pads fail.
Is it implausible to think that contacts OR the 2mm of travel on the Di2 buttons won't degrade over time?
Can the switches in a Di2 shifter be replaced or is the shifter
kaput if here is an out-of-warranty failure?
Do Shimano's Di2 individual components become paperweights like their mechanical counterparts upon failure?
What then, is the theoretical life expectancy of a Di2 component under normal conditions?
And, under adverse conditions?
Can THOSE (
the underlying switches) be real concerns about the Di2 buttons/paddles for the non-sponsored rider who are not concerned about their dexterity when they are fatigued?
Yes, those are a lot of concerns for someone who is unlikely to buy a Di2 drivetrain because 'I' am
less convinced that there is an advantage over what I am currently using than Shimano-and-SRAM users might be convinced that there is any possible advantage to using Campagnolo's mechanical shifters with-or-without Shimano derailleurs!
And so, while the supposed lack of any significant tactile feedback is NOT necessarily a big deal it seemed to be worth being aware of & therefore worth noting ...
OKAY. With THAT out of the way, let me say that once one gets beyond the utility of various components, the cosmetics and/or ergonomics CAN matter ...
And, I can envision that there are some
infidels who do not like the appearance of Campagnolo's components ...
NOT all of the components coming out of Vicenza look good.
But, even if all other things were equal, 'I' would rather have the Campagnolo's electronic thumb lever rather than the Di2's button.
